Description

FLAVOUR ENCAPSULATION
FIELD OF THE INVENTION
The present invention relates to the encapsulation of flavours, more especially to the encapsulation of volatile flavours by a high-boiled sugar glass, and to edible products containing such encapsulated flavours.
BACKGROUND OF THE INVENTION
US-A-5,009,900 describes a process for encapsulation of a composition containing at least one volatile and/or labile component, which process comprises forming a mixture of said composition with:
(a) from about 40 to 80% by weight of a water-soluble, chemically-modified starch having a dextrose equivalent not greater than about 2;
(b) from about 10 to 40% by weight of a maltodextrin having a dextrose equivalent in the range of from about 5 to about 15;
(c) from about 5 to about 20% by weight of corn syrup solids or a polydextrose having a dextrose equivalent in the range of from about 21 to about 42; and (d) from about 5 to about 20% by weight of a mono- or disaccharide, all of said percentages being based upon the total weight of said components (a), (b), (c) and (d); and extruding the mixture to form a glassy matrix having a glass transition temperature of at least 40°C wherein the composition containing at least one volatile and/or labile component is encapsulated.
WO 96/11589 describes a process for the preparation of particulate flavour compositions comprising a flavour oil fixed in a particulate polyol material, which comprises: (a) mixing a mono- or disaccharide, a polysaccharide and water with a minor but flavour effective amount of a flavour oil to form a homogeneous substrate such that the resulting particulate flavour compositions possess a Tg below room temperature; and
(b) extruding said homogeneous substrate at a temperature sufficient to form a melt which on cooling solidifies as a hard rubbery and amorphous material having said flavour oil entrapped therein The above processes, as are many of the prior known processes for encapsulating flavours, require extrusion. In many cases, this requires investment in costly and space-consuming extrusion equipment as well as the know-how to operate the extrusion system.
High boiled sugar glass is predominantly an amorphous glassy matrix at ambient temperature with the sugar in a continuous phase. In contrast, pressed or compressed sweets and tablets, etc. contain sugar particles which are not continuous and any flavour contained therein can be lost easily. We have found, surprisingly, that by using high-boiled sugar glass (e.g. Fox's glacier mint) to encapsulate volatile flavour for use as a flavour protector/carrier, e.g. in edible products such as pressed sweets or tablets, we can use a conventional manufacturing process for the production of high-boiled sweets to produce the sugar glass without the need of expensive extruders. We have found surprisingly that not only does the sugar glass restrict the mobility of flavour molecules at ambient temperatures so that flavour losses are minimised during mixing but also, the flavours are retained during shelf storage.
SUMMARY OF THE INVENTION
According to the present invention there is provided a process for the preparation of an encapsulated flavour composition comprising a flavour encapsulated in a high-boiled sugar glass which comprises boiling the ingredients of a high-boiled sweet to give a syrup, further heating the syrup to reduce the moisture content to below 5% by weight based on the weight of the syrup, cooling the syrup to a temperature from 120° to 80°C, adding the flavour with agitation to encapsulate the flavour, cooling to solidify the encapsulated flavour, and finally particulating the encapsulated flavour.
DETAILED DESCRIPTION OF THE INVENTION
The ingredients of the high-boiled sweet and the amounts in which they are used are well known to the skilled person and generally comprise a mixture of a sugary or non-sugary sweet material with water, e.g. from 0.1-2.5% by weight of water. Examples of sugary sweet materials are sucrose and corn/glucose syrup.
Examples of non- sugary sweet materials include isomalt, lactitol, maltitol and lycasin.
after boiling the ingredients of the high-boiled sweet to give a syrup, the syrup may be further heated to a temperature from 120°c to 160°c to reduce the moisture content, preferably to from 0.1 to 4.5% and more preferably to from 1 to 3% by weight, the actual temperature may depend on the type of cooker used, for example, if an open pan is used, the syrup may conveniently be heated to from 145° to 160°c. if a vacuum cooker is used, the syrup may conveniently be heated to a temperature from 125° to 140°c depending on the vacuum, if a batch cooker is used, the syrup may conveniently be heated to a temperature from 135° to 150°c.
After the water content has been reduced to below 5% , the syrup is preferably cooled to from 110° to 82.5°C, more preferably from 105° to 85°C, and especially from 100° to 87.5°C. The flavour is then added to the syrup with mixing and the syrup cooled further preferably to room temperature, e.g. from 20° to 30°C, to solidify the high-boiled sugar glass containing the encapsulated flavour, e.g. by pouring onto a water-cooled slab.
The flavour is advantageously a volatile flavour which may be in liquid or solid form, e.g.vanilla, orange, chocolate, coffee, cocoa, and especially a flavour oil, e.g. mint oil, orange oil, cinnamon, hazelnut, etc. If desired, a colour or an acid (such as in Foxes fruits (citric and lactic acids) may be incorporated in addition to the flavour. The colour can be any format and may be water soluble, e.g.dyes, pigments or it may be a non soluble fat-based or oil which would be added as a dispersion. The acid may be, for instance, citric, malic, tartaric, lactic or ascorbic acid. The amount of colour will depend on the legal maximum levels permitted and may be any amount up to the maximum for that particular colour or blend of colours. The amount of acid may be from, for example, 0.1-3%. The colour or acid may be added to the sugar glass at the same time as the flavour or separately anytime after heating to 120°C. The acid, with or without the addition of buffer, should be a food-acceptable acid such as the acid used in Fox's fruits. The amount of the flavour added to the cooled syrup should be an amount effective to impart the desired flavour to the edible product in which the encapsulated flavour composition is incorporated. The amount of flavour added may be up to 20%, e.g. from 0.1 to 20%, preferably from 0.5 to 17.5% and more preferably from 2 to 15% by weight based on the weight of the encapsulated flavour composition.
After the flavour has been added and mixed with the cooled syrup to encapsulate it, the encapsulated mix is cooled to ambient temperature and particulated into beads, slabs or a powder. The particle sizes of the beads, slabs and powders depend on the application, e.g. to incorporate into a pressed sweet, this may be less than 1mm. In some cases, they will be added to give a visual impact for the colour and appearance. For visual effect the particle size may be in the range of from 50 microns to 5mm depending on the effect or texture required, to use as a concentrated flavour sugar for beverages, the size will be of any size depending on the dissolving characteristics., Particulation into beads may be carried out by spray chilling/drying. Slabs may be formed by injection moulding or depositing into a mould. Powders may conveniently be obtained by grinding or with addition of a spray drying process.
The present invention also provides an encapsulated flavour composition comprising a flavour encapsulated in a high-boiled sugar glass.
The encapsulated flavour composition may be used in any desired application in edible products.
Accordingly, the present invention also provides an edible product having incorporated therein or covered therewith an encapsulated flavour composition comprising an effective amount of a flavour encapsulated in a high-boiled sugar glass. Preferably, the encapsulated flavour composition is prepared by the process of the present invention.
The amount of encapsulated flavour composition may be from 0.1% to 10% and preferably from 1 to 5% by weight based on the weight of the edible product. The edible products include confectionery, pharmaceutical, beverage or functional products. Confectionery products may include pressed tablets or sweets, chew and hydrocolloid based products. Pressed tablets or sweets conventionally contain mainly granulated sugar together with a binder, a lubricant and a optionally a colour/conventional flavour. Examples of binders are gums such as gum arabic, gelatin or alginates, or they may be starches, sugars or fats. Examples of lubricants are magnesium stearate, stearic acid, oils or fats.
When the encapsulated flavour composition is used to cover the edible product, it can be used to dust, coat or surface enrobe the edible product. In this case, the edible product is preferably a confectionery product.
When used in beverages, the encapsulated flavour composition will allow instant release of flavour when dissolving in water before consumption and the present invention also provides a beverage containing an effective amount of an encapsulated flavour composition comprising a flavour encapsulated in a high- boiled sugar glass.
The encapsulated flavour composition may be also contain a colour or and acid and used as a colour/flavour/acid encapsulated compound in edible products.
The encapsulated flavour composition can encapsulate a flavour to prevent deterioration of flavour intensity and characteristics over time in foods and pharmaceutical products.
High boiled sugar glass being predominantly an amorphous glassy matrix at ambient temperature restricts the mobility of flavour molecules. Hence, this may be able to protect the product from flavour loss leading to maximum flavour retention especially for volatile flavour (e.g. essential oil). This may be especially useful for products which are stored at high humidity and temperature, e.g. in tropical regions or South American climates.
The issue of hygroscopicity could be overcome by adding a small amount, e.g. from 0.1 to 5% by weight of a biopolymer e.g. maltodextrin to increase the glass transition temperature. The depositing conditions may require modification to suit the higher viscosity as a consequence of addition of the biopolymer into a mould whereby "tailing" should be avoided after the flavour addition.
The present invention provides the following advantages:
1) It improves the product quality,
2) It increases the fresh and shelf life of the products,
3) It reduces waste and increases efficiency due to possible use of rework from existing high boiled products,
4) It enables utilization of existing assets, using current high boil process and equipment for production of flavour compounds for foods and pharmaceutical applications,
5) It reduces cost for flavour as losses are minimised. 6) It enhances visual appear and perceived quality.
